	 * ----------------------------------------------------------
	 * These functions use the same 'format' strings as the 
	 * java.text.SimpleDateFormat class, with minor exceptions.
	 * The format string consists of the following abbreviations:
	 * 
	 * Field        | Full Form          | Short Form
	 * -------------+--------------------+-----------------------
	 * Year         | yyyy (4 digits)    | yy (2 digits), y (2 or 4 digits)
	 * Month        | MMM (name or abbr.)| MM (2 digits), M (1 or 2 digits)
	 *              | NNN (abbr.)        |
	 * Day of Month | dd (2 digits)      | d (1 or 2 digits)
	 * Day of Week  | EE (name)          | E (abbr)
	 * Hour (1-12)  | hh (2 digits)      | h (1 or 2 digits)
	 * Hour (0-23)  | HH (2 digits)      | H (1 or 2 digits)
	 * Hour (0-11)  | KK (2 digits)      | K (1 or 2 digits)
	 * Hour (1-24)  | kk (2 digits)      | k (1 or 2 digits)
	 * Minute       | mm (2 digits)      | m (1 or 2 digits)
	 * Second       | ss (2 digits)      | s (1 or 2 digits)
	 * AM/PM        | a                  |
	 *
	 * NOTE THE DIFFERENCE BETWEEN MM and mm! Month=MM, not mm!
	 * Examples:
	 *  "MMM d, y" matches: January 01, 2000
	 *                      Dec 1, 1900
	 *                      Nov 20, 00
	 *  "M/d/yy"   matches: 01/20/00
	 *                      9/2/00
	 *  "MMM dd, yyyy hh:mm:ssa" matches: "January 01, 2000 12:30:45AM"
